From what I’ve read, Hoof and Mouth disease is not fatal to livestock- it only decreases their productivity. And IIRC, humans don’t get sick from it at all, although they can carry it.
So why is it considered such a horrible plauge that the cattle of entire regions must be slaughtered to try to prevent its spread? Isn’t that a greater loss to the cattle industry than the disease itself would be?
It seems like putting people in quarantine for having the flu would be.
